事前に調整されたエッジワイズアタッチメントとメカニクスの科学的エビデンス

The scientific evidence for pre-adjusted edgewise attachments and mechanics.

抄録

序論 固定式矯正装置システムは進化を続けており、これらの改良を裏付ける豊富なエビデンスが出現している。目的 固定式装置のデザインとメカニクスの選択に役立つ比較前向き研究のエビデンスを提示する。同様に、ワイヤーの種類や寸法による明確な優位性も示されていない。考察 レースバックやスペースクロージングメカニクスを含め、固定式装置のアタッチメント、アーチワイヤー、補綴物の選択をサポートする高品質な最新のエビデンスが豊富に確認された。この情報は、日常診療における固定式装置の選択と操作において、エビデンスに基づいた決定を行うために利用することができる。

Introduction Fixed orthodontic appliance systems continue to evolve with a wealth of evidence emerging to underpin these refinements.Aims To present the evidence from comparative prospective research informing the selection of fixed appliance design and mechanics.Design Detailed literature review.Materials and methods An electronic search to identify randomised controlled trials and clinical controlled trials was undertaken using pre-defined search terms.Results Based on high-level evidence, no one bracket system has been proven superior in terms of efficiency or outcome. Similarly, a clear advantage associated with one wire type or dimension has not been shown. The effect of lacebacks in terms of anchorage management appears to be limited, while elastomeric chain and nickel titanium closing coils are associated with similar rates of space closure.Discussion A wealth of high-quality recent evidence to support the selection of fixed appliance attachments, archwires and auxiliaries, including lacebacks and space closing mechanics, was identified.Conclusions There has been a considerable increase in the amount of high-quality evidence informing the choice of pre-adjusted edgewise mechanics in recent years. This information can be used to make evidence-based decisions in the selection and manipulation of fixed appliances during daily practice.
